. -l Claim.

T he invention has relation to paper guide devices, designed to be applied to listing calculators,

v typewriters or the like.

It has been found that thin paper fed'to the cylindrical platen of such machines conforms to the curvature of and usually winds around the platen. t I' The object ofthe invention is to provide means for diverting the paper fromy the'platen to the i l0 usual paper support plate.'

The-invention consists in the novel construction and combination of parts, as set forth in the appended claim.

In the accompanying drawings illustrating the invention: -L

Fig. 1 is aA front elevation of a portion of the carriage of a listing calculator, the paperguide being shown in activev position. j Fig. 2 is a cross section, taken substantially at the middle of Fig. l, the paper guide being shown in* inactive' position.

Fig. 3 is a similar View, the paper guide bein shown in active position. In the drawings, the numeral I designates the usual cylindrical p1aten supported in the carriage of alisting calculator. l'

A roll oi.' tally tape paper 2, suitably supported bythe carriage, is fed upon platen I, through slotted Qpening 3. Paper 2 isv heldfincontactv with the platen by means of feed rollers I, forming part of a guiding assembly 5 located below the platen, the paper passing also beneath guide 6.

The following' novel means are provided to prevent the paper 2 fromcontinuing around the platen I, as said platen is rotated in well known manner, and to divert the paper along the usual carriage back plate 1. i v

`A plate 8 removably supported uponthe face of back plate 1 is provided with a suitable slot 4 0 through which extends button Ill, securedt a curved leaf spring II. Spring II-extendsldownwardly along the face ofV plate 8 and passes through suitable embossments I2' of said plate.

Button I0 vis moved downwardly along slot 9 until spring II contacts the platen I, said spring 5 exing toits normal curved condition as it passes from beneath lower embossment vI2 as shown in Fig. 3.

The normal clockwise rotation of platen I duringva paper feed actionwill force spring I I back- 10 Wards slightly into adjusted position wherein said spring will just contact the surface of platen I4 without exerting pressure thereon..

As rpaper 2 is fed around platen I the forward edge of said paper'will now contact spring II and 15 be guided upwardly along plate 8, suitable veinbossments I3 of said'plate camming the paper outwardly, to prevent engagement thereof with theemhossments I2.

Since full size sheet paper, such as bank statements, etc., are inserted ,aroundplaten I from the face of plate 'I spring II- is first withdrawn by sliding button I0 to the top of slot 9 the lower y -embossment I2 acting to straighten spring II 'and hold said spring atly against plate 8.

I claim:

'I'he combination with a cylindrical rotary platen of a paper guide comprising a'support, a normally curved leaf spring, means to adjustably secure the spring to said support whereby in one 30 adjusted position said spring is flattened againstv said supportvin tangential relation to said platen, and in another adjustedposition of said spring an end thereof is in engagement with the platen at a point'oifset from the plane of said tangential 35 relation, said point being determined by the tendeny of said spring to` assume its curved condition.
